After getting a glimpse of Avast's new mobile security solution a few weeks ago, I just had to dive in and give the app a full review. Avast, the long-awaited marriage of Avast and IT Agents' Theft Aware (see our review), certainly doesn't disappoint. It has an insane number of features, all of which appear to work perfectly, and it sounds like things will only be improving with time.

And did I mention the full-featured, root-enhanced app is completely free with no paid version in sight?

Avast has just launched its Mobile Security app for Android, integrating the pure power of Theft Aware (see our review) with some amazing new features. If you remember, Avast swallowed up ITAgents, the small company behind Theft Aware, back in September and promised to integrate it with its upcoming software. Even in its beta state, Avast's Mobile Security looks to be a very strong contender among the dozens of other security apps floating around in the Android Market.

In the past couple of months, I've covered more than a dozen mobile security apps, carefully weighing the pros and cons of each, and determining their relative values. I've spent time with 17 apps in all, and it's about time to wrap up the series, and tell you, the end user, which apps are your best bet for protecting your Android device(s).

Before I get to the nitty-gritty of which app is best, I think it'd be helpful to review what we've covered so far, to get a clear grasp on each of the solutions we've covered.

Landing at number 16 in the Mobile Security App Shootout is XtraSEC Mobile Security, from developer wedjohn57. XtraSEC is dedicated specifically to loss and theft protection, providing a clean, no frills experience, an intuitive interface, and support for multiple devices.

At A Glance

XtraSEC is certainly a lightweight app, housing most of its power in the app's online interface. XtraSEC comes in both free and paid flavors. The free version lacks Remote Locking, Data Wipe, Battery Info and on demand SIM information, but the paid version comes in at a modest $1.99/year.

Kaspersky, a huge name in computer security, not only protects your home and office computers, but your Android device as well. Kaspersky Mobile Security, now in its 9th revision, is a robust app packing anti-virus, anti-malware, call blocking, and theft/loss protection into one lightweight package.

At A Glance

Kaspersky's security solution for Android comes in a relatively lightweight app, costing only 1.5MB in storage. The app's loss/theft protection relies totally on SMS commands, meaning your phone is still protected even if data is turned off.

The developers behind the already popular ESET Security solutions for various desktop platforms is responsible for the next entry in our Mobile Security App Shootout: ESET Mobile Security for Android. Before we get started with reviewing the app, it's important to note that right now ESET for Android is in its Beta stage, and the app available on the Market is a Release Candidate, meaning it's not quite finished yet. The good news, however, is that the app is free throughout its stages in beta.

Trend Micro, the company that "Secures Your Journey To The Cloud" with an extensive line of security products for home and business, also offers a mobile security solution for Android users, called simply Mobile Security Personal Edition. This app is what we'll be discussing in the thirteenth installment of our Mobile Security App Shootout.

At A Glance

Within Trend Micro's security app we find another smoothly designed, well functioning security solution that sets up quickly and is exceedingly easy to use.

Webroot Software Inc. are the developers behind the popular security solution of the same name for desktops, and have brought the same protection to Android users with Webroot Mobile Security. This app, unlike its desktop counterpart, has features specifically for lost or stolen devices, giving the user the ability to track, lock, and wipe the device remotely from the handy online console.

At A Glance

Webroot Mobile Security has a free version and a paid version coming in at $14.99.

Looking to protect your mobile devices as well as it protects your computer, AVG has cooked up Anti-virus, available in free version, or a Pro offering for a one-time payment of $9.99. It's an app that not only helps you locate your lost device, but also protects your phone or tablet in real time by scanning apps, web pages, and settings to be sure you're safe.

At A Glance

AVG's anti-virus/security app comes in a small package but packs a lot of features.

Overvi3w from Unfairware is our next entry in the Mobile Security App Shootout, bringing a nice set of features for free (and a bevvy of other features with a subscription) in a lightweight, battery-friendly package.

At A Glance

Unlike the past two apps in the Shootout, Overvi3w relies on an online interface to remotely control and receive data from your phone. The app itself installs pretty quickly and is out of your hair after that - it automatically hides itself after setup (if you reboot), making it more secure against clever thieves.
